hi
In centos 8, after installing directadmin, port 2222 does not open

I did the following steps to solve the problem but it was useless:

1:

https://help.directadmin.com/item.php?id=75

---------------------
2:

https://help.directadmin.com/item.php?id=29

---------------------

But I still can't enter 2222
----------------------------------------------------------------------------------------------------------
I saw a strange thing, there is no port in the conf file !!!!!!!!!!!!!!!!!!

Disable the firewall.

The problem was the data center
They had blocked port 2222
